TC 1-93: Calculation of self-luminous neutral scale

To recommend a formula or computational method for an achromatic, neutral or gray scale for self-luminous (i.e. non-reflective) surfaces. (This computation complements CIE Lightness, L*, which serves a similar purpose for reflective surfaces.)

TC 1-91: New Methods for Evaluating the Colour Quality of White-Light Sources

To evaluate available new methods for evaluating the colour quality of white-light sources with a goal of recommending methods for industrial use. (Methods based on colour fidelity shall not be included: see TC1-90).

TC 1-83: Visual Aspects of Time-Modulated Lighting Systems

1. To investigate and report on current research on the perception of visual artefacts of temporally modulated lighting systems, including flicker, the stroboscopic effect and the phantom array effect.

2. Design methodology and gather data on the visibility of temporal artefacts.

3. Build a model for the visibility of temporal artefacts and their dependence on environmental, demographical and lighting parameters.

TC 1-82: The Calculation of Colour Matching Functions as a Function of Age and Field Size

1.Following on from CIE 170-1:2006, to recommend a procedure for calculating XYZ-like colour matching functions from cone fundamentals, as a function of age and field size. 2. To deliver a computer programme for the calculations.

TC 1-81: Validity of Formulae for Predicting Small Colour Differences

TC 1-80: Research Methods for Psychophysical Studies of Brightness Judgements

To report on research methods (both research design and statistical analysis) for psychophysical studies of spatial brightness judgements. The aim is to bring best practices from psychology into the wider awareness of people in the lighting community who wish to use such tools in their own work, to avoid errors that plague the existing literature.

TC 1-77: Improvement of the CIE Whiteness and Tint Equations

To recommend improvements or modifications to the existing CIE Equations for Whiteness and Tint to extend their scope of application to a wider range of instrument conditions and white materials; e.g. various tints and levels of fluorescence.

TC 1-76: Unique Hue Data

TC 1-75: A Comprehensive Model of Colour Appearance

To derive colour appearance models that include prediction of the appearance of coloured stimuli viewed in typical laboratory conditions: that appear as unrelated colours that are viewed under illumination down to scotopic levels that include consideration of varying size of stimulus.

TC 1-70: Metameric Samples for Indoor Daylight Evaluation

TC 1-69: Colour Rendering of White Light Sources:

To investigate new methods for assessing the colour rendition properties of white-light sources used for illumination, including solid-state light sources, with the goal of recommending new assessment procedures.

Chair: Wendy Davis (US).

TC 1-67: The Effects of Dynamic and Stereo Visual Images on Human Health

To write a technical report on the physiological and psychophysical effects of dynamic and stereo visual images in terms of photosensitive seizures.
